Philip Chauncy was a sketcher, amateur photographer and surveyor, working in the Swan River Colony from 1841 to 1853. In this sketchbook Chauncy drew rare portraits of Aborigines from King George Sound. The portraits include one of Wylie, who had accompanied the explorer Edward John Eyre in his attempt to cross the Nullabor Plain in 1841, and a portrait of Wylie’s wife Gelgaran.
